Unfortunately, neither the SQL standard nor JDBC has seen fit to recognize UUIDs as a data type. So that means a second cost to using UUIDs in a database: Dragging those UUID values across the chasm of JDBC + SQL. One one end, we have Java which understands UUID as a built-in class (java.util.UUID). That's good. On the other end, we have Postgres which understands UUID as a native data type. That's good. The problem is in between.
The solution is that JDBC has a trap-door to handle data types unknown to SQL, called simply object. Let's look at an example, a snippet of Java code.
// Generate or obtain data to store in database.
java.util.UUID uuid = java.util.UUID.randomUUID(); // Generate a random UUID.
String foodName = "Croissant";
// JDBC Prepared Statement.
PreparedStatement preparedStatement = conn.prepareStatement( "INSERT INTO food_ (pkey_, food_name_ ) VALUES (?,?)" );
int nthPlaceholder = 1; // 1-based counting (not an index).
preparedStatement.setObject( nthPlaceholder++, uuid );
preparedStatement.setString( nthPlaceholder++, foodName );
// Execute SQL.
if ( !( preparedStatement.executeUpdate() == 1 ) ) {
// If the SQL reports other than one row inserted…
this.logger.error( "Failed to insert row into database." );
}
This code is simpler than you might expect. No need to transform the UUID as textual hex representation on the Java side. No need to cast the value on the Postgres side. By calling the ".setObject" method, and passing an actual UUID value, it all works.
Going the other direction, retrieving a UUID value from the database, call the getObject method and cast the result to a java.util.UUID object. Like so, where `rs` is a ResultSet:
java.util.UUID uuid = ( java.util.UUID ) rs.getObject( "uuid_" );
By the way, if you need to pass an empty or 'nil' value for a UUID, generate a UUID with all bits of all zero values. This is commonly understood to mean "no value" in UUID-speak. One way to generate such a UUID is:
java.util.UUID emptyUuid = new java.util.UUID( 0L, 0L );

ReplyDeleteI'M NOW FULFILL FINANCIALLY BECAUSE OF THE LOAN I GOT FROM LFDS .I would like to bring this to the notice of the public about how i came in contact with LFDS after i lost my job and being denied loan by my bank and other financial institution due to my credit score. I could not pay my children's fees. I was behind on bills, about to be thrown out of the house due to my inability to pay my rent, It was during this period my kids were taken from me by foster care. Then i set out to seek for funds online where i lost $3,670 that i borrowed from friends which i was rip off by two online loan companies. Until i read about:Le_Meridian Funding Service (lfdsloans@outlook.com / lfdsloans@lemeridianfds.com) somewhere on the internet, Still wasn't convince because of what i have been through until a relative of mine who is a clergy also told me about the ongoing loan scheme of LFDS at a very low interest rate of 1.9%% and lovely repayment terms without penalty for default of payment. I have no choice than to also contact them which i did through text +1-989-394-3740 and Mr Benjamin responded back to me That day was the I'M best and greatest day of my life which can never be forgotten when i receive a credit alert of $400,000.00 Usd loan amount i applied for. I utilized the loan effectively to pay up my debts and to start up a business and today i and my kids are so happy and fulfill. You can as well contact them through email: (lfdsloans@outlook.com / lfdsloans@lemeridianfds.com) WhatsApptext helpline: +1-989-394-3740 Why am i doing this? I am doing this to save as many that are in need of a loan not to be victim of scams on the internet. Thanks and God bless you all, I'm Oleksander Artem from Horizon Park BC , Ukrain.

ReplyDeleteYou're absolutely right that using UUIDs as database record identifiers can have several benefits, such as uniqueness, compatibility across different systems, and reduced risk of collisions. However, you've correctly pointed out that there can be challenges when working with UUIDs in the context of JDBC and SQL.
ReplyDeleteWhile UUIDs are not recognized as a standard data type in SQL or JDBC, there are ways to handle them effectively. Here are a few approaches you can consider:
Storing UUIDs as String or Binary: Since UUIDs are typically represented as strings (e.g., "550e8400-e29b-41d4-a716-446655440000") or binary data, you can store them as such in your database. In the case of Postgres, you can use the uuid data type or store the UUID as a string or binary data in a column.
Converting UUIDs in SQL: If you're working with databases that don't have native UUID support, you can store UUIDs as strings or binary data in a column and handle conversions in your SQL queries. For example, you can use functions like UUID_TO_BIN or BIN_TO_UUID to convert between binary and string representations of UUIDs.
Custom Mapping in JDBC: JDBC provides mechanisms to handle non-standard data types through custom mappings. You can create a custom mapping between the UUID class in Java and the appropriate data type in your database. This allows you to work with UUIDs seamlessly in your Java code while transparently converting them to the corresponding database representation.
Here's an example of registering a custom mapping for UUIDs in JDBC:
java
// Assuming you have a connection object named 'connection'
java.util.Map> typeMap = connection.getTypeMap();
typeMap.put("uuid", java.util.UUID.class);
connection.setTypeMap(typeMap);
By registering the custom mapping, you can retrieve UUID values from the database using the java.util.UUID class.
It's worth noting that the specific approach you choose may depend on the database system you're using, as different databases have varying degrees of support for UUIDs.
While working with UUIDs in the JDBC and SQL ecosystem may involve some additional considerations and conversions, it's certainly possible to utilize UUIDs effectively in your database design. The benefits they provide, such as uniqueness and compatibility, often outweigh the challenges involved in handling them across different layers of your application.
